Refusing to let this second chance go to waste, he summons a small bone to use as a shield against your attacks, his eyes become hollow circles and he begins the second part of the fight. Sans then becomes confused as to why he hasn't yet turned to dust, checking his hp to see he has a small fraction of health left, allowing him to stay alive. He then begins to explain why he acts so lazy and is so nihilistic, it's due to the fact that the anomaly would just erase it all in the end, so there was no real point to ever giving anything a real effort. If you choose to fight, Sans will get hit, falling to the ground as he begins to bleed from the scar.

With no other choice, Sans fights them, now no longer holding anything back, using every one of his abilities to its fullest, including his new orange bones, but in the end, he becomes tired from dodging, giving Frisk the choice to give mercy. Now fully convinced, Sans readies himself to confront Frisk after being taught a new ability, it being orange attacksĪfter killing everyone, Frisk is confronted by Sans in the Last Corridor, Sans tells them everything he is aware of and tries to guilt-trip them, but sadly fails.

Skeptical at first, Sans refused to believe so Gaster then resurfaced past Genocide timelines throughout Sans' mind. Sans recognized who this was while he was informed of Frisk's intentions to forever use monsters as their puppets and slaughter them. On the 30th Genocide Run, Sans was napping at his sentry station, as usual, when a figure appeared throughout his fantasies. (This contains spoilers for UNDERTALE: Last Breath!
